Russia Installs Early Warning Radar in Syria for Iran
If this is not an indication of whose side Russia is on in the Iranian nuclear weapons project, then, I do not know what would be.
The Russians have upgraded their radar systems at the Jabal Al Harrah electronic and surveillance station, south of Damascus, opposite Israel’s Sea of Galilee. The system's range extends to all parts of Israel and Jordan, the Gulf of Aqaba and northern Saudi Arabia. What this does for Iran, for which Russia has an economic vested interest in, it provides an early warning system to alert them when Israeli planes are on their way, should this occur. Even the Russian-equipped Syrian radar on Lebanon’s Mount Sannine is now connected to the Jabal Al Harrah facility in Syria. This will allow them to monitor naval ship movements all the way to Cyprus and Greece.
The upgrades now make it very hard for any sort of surprise attack by Israeli aircraft that would fly across Jordan, Iraq, on their 1000 miles flight into Iran. Iranian weapons would have more than sufficient warning from the Russian\Syrian manned radar sites. It seems the upgrades happened when Iran complained about the lack of response time and the effectiveness of the existing system filled with gaps.
If there is a war, obviously Russia will be on the side of Iran. China may be as well since much of their oil comes from Iran.
